Description

Discarding chamfering blade

This creation is about a chamfering of the workpiece material, a modified structure of the trimming of the trimming, and in particular, a discarded chamfering blade of a discarded structural design.

Generally, after the workpiece is drilled, a chamfering tool is used to chamfer the hole, or chamfering or trimming the edge of the workpiece to eliminate the edge of the hole or the edge of the workpiece. material.

The conventional chamfering cutter 5, as shown in FIG. 9, includes a cutter bar 51 and a conical cutter head 52 disposed at one end of the cutter bar 51. The conical cutter head 52 is provided with at least one siping 521. The sipe 521 is formed to form a cutting edge 522 on the side of the sipe 521 for chamfering the cutting hole or chamfering the edge of the workpiece.

However, the material of the chamfering cutter 5 described above is made of high speed tool steel (HSS) or other tool materials, and the sipe 521 is formed by grinding, so the processing speed of the sipe 521 is slow. Moreover, the processing cost is high, which directly affects the manufacturing cost of the chamfering tool 5. However, once the cutting edge 522 of the chamfering tool 5 is cracked during the processing, it must be discarded and cannot be used any more, so the conventional chamfering tools are regarded as It is a consumable item that cannot be reused, highlighting the waste of materials and increasing production costs.

In addition to this, there is also a design using a disposable blade structure, the tool body The large-sized, discarding blade is placed on one side of the tool. This single-blade and eccentric setting is prone to eccentric shaking or vibration, so the rotation speed of the tool is slow, and the design of the single blade has a low cutting removal rate. The chamfering cutting efficiency is low and the processing speed is slow.

The chamfering tool made by the high-speed tool steel (HSS) has the disadvantages of high processing cost and high speed due to the high processing cost of the sipe, and it must be discarded after the cutting edge of the chamfering tool is broken during the machining process. Reuse is not only wasteful but also increases production costs.

The present invention is a discarding chamfering blade, which is mainly provided with a hole for the discarding blade, and the hole is for locking the chamfering blade to lock the cutter, and the discarding chamfering blade has a V shape, and the discarding One end of the chamfering blade is provided with a conical cutter head, and a plurality of chip flutes are arranged along the tapered circumference ring of the conical cutter head, and one side of the chip flute is a blade, forming a plurality of cutting edges. Discarding chamfering blades for continuous cutting.

The present invention has a tapered cutter head at the end of the discarding chamfering blade, and the tapered cutter head has a plurality of cutting edges designed to increase the material removal rate by several times and change the design of the conventional chamfering cutter. Form, chamfering time is reduced and productivity is improved.

Referring to Figures 1 to 3, the presently disposed chamfering blade 10 is provided with a hole 11 for locking the chamfering blade 10 to the cutter 20 (as shown in Figures 4 and 5). The discarding chamfering blade 10 has a V shape, and one end of the discarding chamfering blade 10 is provided with a conical cutter head 12, and a plurality of chips are arranged along the tapered circumference ring of the conical cutter head 12. The groove 13 has one side surface of all the cutting edges 13 and is formed by a plurality of cutting edges for the continuous cutting of the chamfering blade 10.

Referring to FIGS. 4 and 5, the artificial chamfering blade 10 is mounted on the top and side views of the cutter 20. The discarding chamfering blade 10 is provided with a multi-blade tapered cutter head 12 at one end. This design is the first in the tool industry, and the tool 20 can be used in conjunction with conventional discarded engraving tools, which is very convenient for the user and saves the cost of purchasing the tool 20.

Referring to Fig. 6, the disposable chamfering blade 10 is capable of performing a general hole chamfering operation or, as shown in Fig. 7, performing a chamfering work of the workpiece or trimming the burr.

Referring to Figure 8, an embodiment of the tapered cutter head 12 of the disposable chamfering insert 10 is modified such that the angle θ of the tapered cutter head 12 is varied to accommodate different processing conditions.

Since the chamfering tool of the present invention is firstly designed to use a discarding structure, the discarding chamfering blade 10 can be quickly replaced when the discarding chamfering blade 10 is passivated or damaged, and the cutter 20 can continue to be used for the user. Cost saving, in addition, the structure of the tool 20 is very simple, and there is no eccentric shaking or vibration when rotating at a high speed, and a multi-blade discarding blade knot is used. With the design of the cutting edge and the high cutting speed and the fast feed rate, the processing speed can be improved by 2~4 times, and the processing efficiency is effectively improved.

By the foregoing description, the present invention is provided with a tapered cutter head at the end of the discarding chamfering blade, the tapered cutter head having a plurality of cutting edges, which is different from the conventional use of only a single discarding blade. Designed to use chamfering tools made of full-speed steel or other tool materials, which reduces manufacturing costs and increases material removal rates by several times, changing the shape of custom-made chamfering tool designs, chamfering The construction time is reduced and the productivity is improved. This structural design is the first in the chamfering tool industry, and it is novel and innovative.

However, the above is only a preferred embodiment of the creation of the industry, and all changes in the scope of the patents are subject to the scope of this patent.
